I honestly thought I was th only one who found those classes you mentioned boring, I have similar experience especially in chemistry, the teacher just talks and whether we get it or not, listening us just like watching a Chinese movie without subtitles.

But physics and math is interactive and fun. The most important step to me that you've mentioned above making the class interactive, I love sharing ideas and opinions and other kids do to, so surely it keeps the class going and fun and makes a child wish it would never end.

Use of real life examples are and amazing way too, it helps break down hard and seemingly bogous information into simpler terms. I've learnt a lot from your post you know. Hope to hear from u soon.
